WHAT WORKS: As good of a setting bestiary as I have ever seen. The art is a mix of great color pieces and well-done pencil sketches, a combination that probably works better than it should. Some of the entries, like Assassins, have unique abilities that serve as a helpful reminder that not all adversaries need to come off a shopping list of powers and abilities. If you don't mind the over abundance cold-related enemies, many of these entries can be used in any Savage Worlds fantasy game with a little re-skinning.
WHAT DOESN'T WORK: Really just an odd bit or two...for instance, there's an agile, undead creature that can only be killed by being grappled...but there's never a reason given as to WHY a grapple does automatic damage to it. There's still that whole "three book buy-in", but looking at the sheer amount of information crammed into the first two thus far, I'm starting to see why it had to happen that way.
CONCLUSION: You might be happy with the Orc entry from the Savage Worlds rulebook. I love "Orc" being divided into 13 specialized archetypes, then further modified by the nine different tribes. It's just how I'm wired. The Hellfrost Bestiary takes the awesome of Savage Worlds and gives me that extra bit of mechanical goodness I love, rather than giving me a dozen entries and advice on just re-skinning orcs every time I want something mean and humanoid. Great product that makes me really want to run Hellfrost (I have a love-HATE relationship with wintery stuff...as in, I think winter is pretty much hell, but I love it from a setting/storytelling standpoint). Highly recommended even if you're just a Savage GM with the extra money to spare and stumped on monsters.
